Why choose a single ply system on pitched roof?
While single ply membranes are traditionally associated with flat roofs, they are increasingly being specified for pitched or sloped roof applications. These systems offer a lightweight, durable, and watertight solution for roofs with inclinations typically ranging from 5° to 35°, depending on the membrane type and installation method.
Application methods of single ply membrane on pitched roofs
When applying single-ply membranes to pitched roofs, the choice of installation method depends on factors such as roof slope, wind load, substrate type, thermal performance requirements, and aesthetic considerations. RENOLIT ALKORPLAN roofing products offer a range of coloured or metal-like membranes to achieve the appearance of traditional roofing materials. Such solutions are lightweight and cost-effective.
A RENOLIT ALKORPLAN Design profile is highly recommended to get a higher aesthetical result.
